Digital Quantum Simulation of a (1+1)D SU(2) Lattice Gauge Theory with Ion Qudits [PDF]
PRX QuantumWe present a quantum simulation strategy for a (1+1)-dimensional SU(2) non-Abelian lattice gauge theory with dynamical matter, a hardcore-gluon Hamiltonian Yang-Mills, tailored to a six-level trapped-ion-qudit quantum processor, as recently ...

Induced QCD II: numerical results
Journal of High Energy Physics, 2019 We numerically explore an alternative discretization of continuum SU(N c ) Yang-Mills theory on a Euclidean spacetime lattice, originally introduced by Budzcies and Zirnbauer for gauge group U(N c ).

N $$ \mathcal{N} $$ = 1 Super-Yang-Mills theory on the lattice with twisted mass fermions
Journal of High Energy Physics, 2021 Super-Yang-Mills theory (SYM) is a central building block for supersymmetric extensions of the Standard Model of particle physics. Whereas the weakly coupled subsector of the latter can be treated within a perturbative setting, the strongly coupled ...

Renormalization group theory of nematic ordering in d-wave superconductors [PDF]
, 2008 We examine the quantum theory of the spontaneous breaking of lattice rotation symmetry in d-wave superconductors on the square lattice. This is described by a field theory of an Ising nematic order parameter coupled to the gapless fermionic ...

Fermion-bag inspired Hamiltonian lattice field theory for fermionic quantum criticality [PDF]
Physical Review D, 2019 Motivated by the fermion-bag approach, we construct a new class of Hamiltonian lattice field theories that can help us to study fermionic quantum critical points, particularly those with four-fermion interactions.

Simulating quantum field theory with a quantum computer [PDF]
Proceedings of The 36th Annual International Symposium on Lattice Field Theory — PoS(LATTICE2018), 2018 Forthcoming exascale digital computers will further advance our knowledge of quantum chromodynamics, but formidable challenges will remain. In particular, Euclidean Monte Carlo methods are not well suited for studying real-time evolution in hadronic ...

A single-particle framework for unitary lattice gauge theory in discrete time
New Journal of Physics, 2022 We construct a real-time lattice-gauge-theory (LGT)-type action for a spin-1/2 matter field of a single particle on a $(1+1)$ -dimensional spacetime lattice.
